Product Introduction: The reagent kit provides a simple, fast, and efficient method for extracting genomic DNA from blood samples. In the presence of high salt, DNA binds to the surface of silica coated Magheads. After rinsing, high-purity DNA is eluted in Buffer EB or deionized water. The purified DNA has good purity (A260/280 ratio between 1.7-1.9) and high integrity (>15 kb), and can be used for downstream experiments such as second-generation sequencing, quantitative PCR, and chip detection. Self provided instruments and reagents 1) Constant temperature mixer 2) 2/15 ml magnetic frame 3) 32 channel nucleic acid extractor 4) 96 channel nucleic acid extractor 5) 96 DW Plate 6) 8 channel Comb 7) Spin tips pack 8) Anhydrous ethanol Preparation and important precautions before the experiment 1.Before the first use, add anhydrous ethanol to Buffer CW1, Buffer GW1, and Buffer GW2 according to the label of the reagent bottle and mark them properly. 2.Magheads are strictly prohibited from freezing or centrifugation. Freezing and centrifugation may cause irreversible damage to Magheads. Operation steps I. Manual single tube operation 1. Use punching forceps to take 1 blood spot with a diameter of 6 mm or 4 blood spots with a diameter of 3 mm (depending on the actual situation) from the blood spot and place them in a 2.0 mL centrifuge tube. 2. Add 40 to the centrifuge tube μ L Protein K and 300 μ L Buffer WSL, then place the centrifuge tube on a constant temperature mixer at 75 ℃ and 1200 rpm, shake and crack for 45 minutes to form Lysate. Remove the centrifuge tube from the constant temperature mixer, centrifuge briefly, and take the supernatant. Attention: If there is no constant temperature mixer, vortex the centrifuge tube for 10 seconds and incubate it in a 75 ℃ water bath for 30 minutes. During this period, vortex every 10 minutes for 10 seconds. 3. Suck the supernatant into a new 2.0 mL centrifuge tube and add 300 μ L Buffer MSL, 300 μ L isopropanol and 20 μ L Magheads V3. Afterwards, place the centrifuge tube on a constant temperature mixer at 25 ℃ and 1600 rpm, shake and crack for 15 minutes, or invert the centrifuge tube and mix continuously for 15 minutes. 4. Place the centrifuge tube on a magnetic stand and let it stand for 1 minute. After Magheads are completely adsorbed on the side wall of the centrifuge tube, discard the solution thoroughly (keep the centrifuge tube fixed on the magnetic stand). 5. Remove the centrifuge tube from the magnetic frame and add 900 μ L Buffer CW1 (please check if anhydrous ethanol has been added before use), vortex point shake for 1 minute or vortex shake for 5 seconds, and then place it on a constant temperature mixer at 25 ℃ and 1600 rpm to shake and mix for 2 minutes (ensure that Magheads are in a mixed state during the shaking process). Afterwards, place the centrifuge tube on a magnetic stand and let it stand for 1 minute. After Magheads are completely adsorbed on the side wall of the centrifuge tube, gently invert the magnetic stand and wash the impurities on the centrifuge tube cover to completely discard the solution (keep the centrifuge tube fixed on the magnetic stand). 6. Remove the centrifuge tube from the magnetic frame and add 500 μ L Buffer GW1 (please check if anhydrous ethanol has been added before use), vortex point shake for 1 minute or vortex shake for 5 seconds, and then place it on a constant temperature mixer at 25 ℃ and 1600 rpm to shake and mix for 2 minutes (ensure that Magheads are in a mixed state during the shaking process). Afterwards, place the centrifuge tube on a magnetic stand and let it stand for 1 minute. After Magheads are completely adsorbed on the side wall of the centrifuge tube, gently invert the magnetic stand and wash the impurities on the centrifuge tube cover to completely discard the solution (keep the centrifuge tube fixed on the magnetic stand). 7. Remove the centrifuge tube from the magnetic frame and add 900 μ L Buffer GW2 (please check if anhydrous ethanol has been added before use), vortex point shake for 1 minute or vortex shake for 5 seconds, then place it on a constant temperature mixer at 25 ℃ and 1600 rpm, shake and mix for 2 minutes (ensure that Magheads are in a mixed state during the shaking process). Afterwards, place the centrifuge tube on a magnetic stand and let it stand for 1 minute. After Magheads are completely adsorbed on the side wall of the centrifuge tube, gently invert the magnetic stand and wash the impurities on the centrifuge tube cover to completely discard the solution (keep the centrifuge tube fixed on the magnetic stand). 8. Remove the centrifuge tube from the magnetic frame and add 300 μ After shaking with 75% ethanol for 1 minute or 5 seconds, place the mixture on a constant temperature mixer at 25 ℃ and 1600 rpm for 2 minutes (ensure that the Magheads are in a mixed state during the shaking process). Afterwards, place the centrifuge tube on a magnetic stand and let it stand for 1 minute. After Magheads are completely adsorbed on the side wall of the centrifuge tube, gently invert the magnetic stand and wash the impurities on the centrifuge tube cover to completely discard the solution (keep the centrifuge tube fixed on the magnetic stand). 9. Keep the centrifuge tube fixed on the magnetic frame, use a pipette to further remove the solution from the bottom and cover of the centrifuge tube, and then leave it at room temperature for 5-10 minutes to allow the ethanol to evaporate completely. 10. Remove the centrifuge tube from the magnetic frame and add 50-200 μ L Buffer EB. Vortex oscillation causes the magnetic beads to completely suspend in the eluent and then place them on a constant temperature mixer at 56 ℃ and 1600 rpm for 10 minutes of shaking and elution, or incubate the centrifuge tube in a 56 ℃ water bath for 10 minutes, with vortex oscillation every 3 minutes for 10 seconds. 11. Place the centrifuge tube on a magnetic stand and let it stand for 2 minutes. After Magheads are completely adsorbed on the side wall of the centrifuge tube, transfer the eluent to a new centrifuge tube using a pipette and store at -20 ℃ for later use. II. Matching with CWE2100 1. Use punching forceps to take 1 blood spot with a diameter of 6 mm or 4 blood spots with a diameter of 3 mm (depending on the actual situation) from the blood spot and place them in a 2.0 mL centrifuge tube. 2. Add 40 to the centrifuge tube μ L Protein K and 300 μ L Buffer WSL, then place the centrifuge tube on a constant temperature mixer at 75 ℃ and 1200 rpm, shake and crack for 45 minutes to form Lysate. 3. Add the corresponding reagents to the 96DW deep well plate according to the table below.
